Underground coal gangue separation equipment

Abstract

The invention discloses underground coal gangue separation equipment. The underground coal gangue separation equipment comprises a base and an overturning plate arranged above the base; and a movable plate is connected into the base in a lifting manner, a material conveying belt is arranged on the movable plate, soft rubber plates are symmetrically and movably connected to the material conveying belt, fixing blocks are fixedly connected to the two ends of each soft rubber plate, and the fixing blocks are matched with each other. A cylinder is fixedly connected to the overturning plate, the upper end of the cylinder penetrates through the overturning plate and is fixedly connected with a conical cylinder, a rotating rod is fixedly connected into the cylinder, a spiral material pushing plate is fixedly connected to the rotating rod and matched with the inner side wall of the cylinder, and a rotating block is fixedly connected to the upper end of the rotating rod. According to the underground coal gangue separation equipment, coal scraps and coal gangue in coal raw materials can be conveniently sorted out for transportation treatment, and convenience is brought to workers.

Description

technical field [0001] The invention relates to the technical field of coal gangue treatment, in particular to underground coal gangue sorting equipment. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing process, so it is necessary to separate the coal gangue from the coal raw materials that have been excavated. However, The existing underground coal gangue sorting equipment is inconvenient to scrape off the coal dust attached to the coal gangue during the processing of coal raw materials, so some coal dust will remain on the sorted coal gangue, which is inconvenient for ...

AI Technical Summary

Problems solved by technology

Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing process, so it is necessary to separate the coal gangue from the coal raw materials that have been excavated. However, The existing underground coal gangue sorting equipment is inconvenient to scrape off the coal dust attached to the coal gangue during the processing of coal raw materials, so some coal dust will remain on the sorted coal gangue, which is inconvenient for the staff to carry out At the same time, the existing underground coal gangue sorting equipment is inconvenient to align and transport after the coal debris and coal gangue are sorted out, which increases the difficulty for the staff to transport the sorted coal debris and coal gangue
